Species ca. 15 (2 in the flora): primarily neotropical, some in Africa, introduced elsewhere in Eastern Hemisphere.

The name Nesoris bicolor Rafinesque was based on a yellow-farinose plant from Florida and presumably represents a species of Pityrogramma . A type has not been located, and C. S. Rafinesque's (1836[--1838]b, part 4) description is not precise enough to permit equation of this name with modern nomenclature. No yellow-farinose Pityrogramma has since been reported from Florida.

Pentagramma has been segregated from Pityrogramma (G. Yatskievych et al. 1990) and comprises what was the Pityrogramma triangularis (Kaulfuss) Maxon complex.
